GUIDE-C if:

To all 'whom 'it may concern.'

lBe it known that I, FRANK M. VAwTER,

. a citizen of the United States, residing at facture and attractive inappearance,

Benton Harbor, Berrien. county, Michigan, have invented new and usefulImprovements in Guide-Cards, of which the following is a specification.Y y

My invention, as will beunderstood from the description and explanationhereinafter givcn, is particularly adapted for application to the indexor guide-cards of vertlcal ling systems now in extensive use for manyurposes, mg used upon the indexes of books, particularly those of aheavy and substantial character, and in other cases where sheets orcards are plrovided with projecting tabs whereby the s eets are adaptedto be turned or separated manually. :I have therefore illustrated andwill describe my invention with reference to a set of guide cards suchas are commonly used for vertical filing or in card indexes, but withoutintention of limitin my invention narrowlyv thereto.

vThe object of my invention is to provide a projecting manipulating tabwhich shall be simple, strong, durable, cheap to manu in general, shallyfu1fil,in a maximum de grec, all the requirements ofsuch tabs. To

this end I have devised the novel structure hereinafter described, andmy invention consists in the construction, arrangement and character ofthe different parts of-such structure, the essential elements 4of whichare recited in the appended claims. y

Of the drawing Figure 1 is a fragmentary face view of the tab andadjacent portion of a guide card, the tab'being shown somewhat larger insize than those in common use; t Fig. 2 is a sectional'view takencentrally of the sheet and looking in the same direct1on;

Fig. 3 is an enlarged section on the line 3-3 of Fig. 1; and Fig. 4 is aview of the top portions of a set of guide cards to which my inventionis shown applied.

The same reference characters indicate the same parts in all the- -gures`of the drawing. p f

It has heretofore been proposed to reinforce tabs of guide cards such asthose to which m invention relates with a facing of sheet ce uloidfolded to extend over and Specification of Letters Patent.

cover the o posite faces ofthe tab, but in practlce it 1s found thatwhile such a reinforcement is strong, sanitary and attractive card, thecelluloid and wire being cemented.

to the card b any suitable cement. The wire length a ords a smooth,hard, rounded surface around which the celluloid facin curves and bywhich it is rigidly supporte in such manner that it cannot be crushedand sharply creased, either in the manufacture of the tab orsubsequently, and is stifened so that in handlin the card the edge ofthe card is restraine against bending and iexing, with the result thatthe ce uloid will not crack along the edge as in the case of the priorform of construction mentioned.

It is obvious that while my Yinvention is particularly valuable asapplied to a facing or reinforcement of sheet celluloid, it may alsov beused lto advantage with other sheet material, as paper, or cloth, ifdesired, and will give increased strength and durability to suchstructures. It isy further obvious that it may be applied to guide orindex tabs wherever used, whether on the guide cards of vertical filingsystems, or elsewhere.

I claim: K l

1. A guide card for vertical ling systems and the like and formed with aro]ecting tab portion, said card having a fo ded sheet f celluloidfacing cemented to the opposite faces of said tab portion and alsohaving a length of round wire interposed between said facing and theedge of said tab portion along the foldin line of the facing.

2. A ide car for vertical filing stems `sand the like and formed with apro]ecting tab portion, said card having a folded facing of sheetmaterialwemented to the oposite faces of said tab portion and also avinga length of wire interposed between said facing and the edge of said tabportion along the foldingrline of the facing.
